including the PF4MNA and FB4C series

using this HVAC heater band on 208V will result in a lower wattage output (approximately 68W)

the CPM-1 logic is designed to monitor cycle timing and protect the compressor from rapid cycling

providing a stable 5:1 turndown ratio for consistent temperature control without the hysteresis common in motor-driven butterfly valves

the blades are precision-balanced to minimize vibration and prevent premature motor bearing fatigue

Field Controls 02723101 Control Refrigerant including the PF4MNA and FB4CThe Field Controls 02723101 (Model 7" RC) is a standard issue barometric draft control engineered for residential and commercial oil or coal fired heating equipment. As a veteran grade draft regulator, it stabilizes the static pressure within the flue, counteracting changes in barometric pressure, wind velocity, and ambient temperature that disrupt combustion. This unit is calibrated for a precise draft range of . 02"wc to . 08"wc and is designed for
